Résolu Erreur lors du cassage de blocs
-
Bonjour j’ai un problème très bizarre puisque dés que je casse une tête de squelette au sol, le jeu crash avec cette erreur:
http://pastebin.com/9zMr72ZeEt voici le code qui correspond je pense!:
[font=Courier New@SubscribeEvent ]public void smeltBlockWithFirePickaxe(BlockEvent.HarvestDropsEvent event) { int quantityMultiplier%(#cc7832)[; ] EntityPlayer entityPlayer = event.harvester%(#cc7832)[; ] Block block = event.block%(#cc7832)[; ] if(entityPlayer.inventory.hasItem(IceNFire.*wandExtendCapture*) || entityPlayer.inventory.hasItem(IceNFire.*wandOfCapture*)) quantityMultiplier = 2%(#cc7832)[; ]%(#cc7832)[ else ] quantityMultiplier = 1%(#cc7832)[; ] if(entityPlayer.inventory.getCurrentItem().getItem() == IceNFire.*firePickaxe*) { if(block == Blocks.*iron_ore*) { event.drops.remove(0)%(#cc7832)[; ] event.drops.add(new ItemStack(Items.*iron_ingot*, 1 * quantityMultiplier))%(#cc7832)[; ] } else if(block == Blocks.*gold_ore*) { event.drops.remove(0)%(#cc7832)[; ] event.drops.add(new ItemStack(Items.*gold_ingot*, 1 * quantityMultiplier))%(#cc7832)[; ] } else if(block == IceNFire.*fireOre*) { event.drops.remove(0)%(#cc7832)[; ] event.drops.add(new ItemStack(IceNFire.*fireIngot*, 1 * quantityMultiplier))%(#cc7832)[; ] } else if(block == IceNFire.*iceOre*) { event.drops.remove(0)%(#cc7832)[; ] event.drops.add(new ItemStack(IceNFire.*iceIngot*, 1 * quantityMultiplier))%(#cc7832)[; ] } else if(block == Blocks.*stone *|| block == Blocks.*cobblestone*) { event.drops.remove(0)%(#cc7832)[; ] event.drops.add(new ItemStack(Blocks.*stone*, 1))%(#cc7832)[; ] } } } -
dès que je casse une tête de squelette ou dès que tu casse n’importe quel bloc sans avoir d’item en main ?
La ligne 28 de ta classe je suppose que celle-ci :
if(entityPlayer.inventory.getCurrentItem().getItem() == IceNFire.firePickaxe)
?
Il te manque un null check, entityPlayer.inventory.getCurrentItem() est null si le joueur n’a rien en main donc faire un .getItem() cause un NPE (NullPointerException)
Solution :
if(entityPlayer.inventory.getCurrentItem() != null && entityPlayer.inventory.getCurrentItem().getItem() == IceNFire.firePickaxe) -
Merci pour la réponse, à la ligne 28 j’ai:
%(#a9b7c6)[[font=Courier New]if](entityPlayer.%(#9876aa)[inventory].hasItem(IceNFire.%(#9876aa)[*wandExtendCapture*]) || entityPlayer.%(#9876aa)[inventory].hasItem(IceNFire.%(#9876aa)[*wandOfCapture*]))et j’ai modifié
%(#a9b7c6)[[font=Courier New]if](entityPlayer.%(#9876aa)[inventory].getCurrentItem().getItem() == IceNFire.%(#9876aa)[*firePickaxe*])en
%(#a9b7c6)[[font=Courier New]if](entityPlayer.%(#9876aa)[inventory].getCurrentItem() != %(#cc7832)[null ]&& entityPlayer.%(#9876aa)[inventory].getCurrentItem().getItem() == IceNFire.%(#9876aa)[*firePickaxe*])Mais ça n’a rien changé
Et seulement quand je casse une tête de squelette avec ou rien en main c’est pareil
Et je remarque que ça me fait pareille si je casse le bloc en dessous d’une herbe ou d’un panneau. -
Dans ce cas le NPE est sur la ligne :
if(entityPlayer.inventory.hasItem(IceNFire.wandExtendCapture) || entityPlayer.inventory.hasItem(IceNFire.wandOfCapture))
Maintenant faut trouver quel objet est null.
Modifies ton code comme ça :if(entityPlayer. inventory. hasItem(IceNFire. wandExtendCapture) || entityPlayer. inventory. hasItem(IceNFire. wandOfCapture))Et dit moi sur quelle ligne exactement il y a le NPE avec cette modification.
-
essaye de faire drops.clear() au lieu du remove j ai eu des NPE aussi avec cette methode

Voici mon nouveau code:

Le code ne correspond pas : ligne 28 tu n’as aucune référence à un objet, même si entityPlayer est null, le problème serai à la ligne 29.
Renvoi la fonction entière et le crash report correspondant.

Ta variable entityPlayer semble être null.
Donc event.harvester l’est aussi, je fais regarder vite fait. -
Eh bien, j’ai rajouter un
if(entityPlayer != null)Et ca s’emble marché
-
Ok parfait. Mais c’est quand même étrange que le joueur est null.
-
robin, je me permet de rebondir, car j’ai remarquer un bug similaire sur les condition du type :
if(entityPlayer.inventory.getCurrentItem() != null && entityPlayer.inventory.getCurrentItem().getItem() == IceNFire.firePickaxe)J’ai personnellement était constamment obliger de séparer en deux condition distincte (d’abord vérifier si c’est null, et si ça ne l’est pas faire un second bloque condition avec la bonne condition) :
if(entityPlayer.inventory.getCurrentItem() != null) { if(entityPlayer.inventory.getCurrentItem().getItem() == IceNFire.firePickaxe) { // ici les fonction } } -
Les deux reviennent au même.
-
A l’exception que j’avais systématique un crash avec la premier méthode… Eclipse semblais effectuer les deux opérations séparement, puis vérifier le “ET” après, du coup il plantais comme il tentai de vérifier une variable null.
Ça pourra peu être dépanner quelqu’un si il ont un crash similaire ^^
-
Normalement non. Le code une fois compilé est sous la forme d’instructions qui se suivent, dans une condition s’il n’y a que des && et que la première condition est fausse, il passe directement à la suite.
